Something like this? 

mkdir /mnt/part1
mkdir /mnt/part2
mount -t ext3 /dev/hda2 /mnt/part1
mount -t ext3 /dev/hda7 /mnt/part2
cp -av /mnt/part1 /mnt/part2
[copious output]
umount /mnt/part1
mkreiserfs /dev/hda2
mount -t reiserfs /dev/hda2 /mnt/part2 -o noatime,notail
cp -av /mnt/part2 /mnt/part1
[copious output]
umount /mnt/part1
umount /mnt/part2
rmdir /mnt/part1
rmdir /mnt/part2
vi /etc/fstab

With my own system, I have seperate partitions for /home, /tmp, /usr, /var, 
/boot, and /, all previously in ext3. I changed fstab to mount these all as 
ext2 instead, and converted my /home to reiserfs using the process above (or 
close to). Ardour runs much nicer now.
